Abstract
Description
Technical Field
[0001] The present invention relates to the field of new energy power generation technology, and specifically to a device and method for generating electrical energy by utilizing the reaction between water mist and electrode sheets. The device and method are particularly suitable for scenarios such as small-scale off-grid power generation and power supply for portable electronic devices. Background Art
[0002] With the development of green energy technology, finding efficient, environmentally friendly and low-cost power generation methods has become a research hotspot. Traditional chemical batteries have the problems of short life and high pollution. Fuel cells are efficient but complex in structure and expensive. Systems that electrolyze water to produce hydrogen and then generate electricity require additional energy input. In the existing technology, devices that generate electricity by directly reacting water with electrodes mostly rely on the electrolysis of liquid water or the gas reaction of fuel cells. They have shortcomings such as limited reaction interface, low energy conversion efficiency and large device size. For example, traditional water electrolysis devices require external power supply, while power generation devices that directly utilize water reactions often have insufficient output power density due to low mass transfer efficiency.
[0003] Therefore, there is an urgent need for a device and method that has a simple structure, does not require external energy input, and utilizes the interface reaction between water and electrodes to efficiently generate electricity, so as to solve the problems existing in the existing technology. Summary of the Invention
[0004] Purpose of the invention: The purpose of the present invention is to provide a power generation device and method based on the reaction between water mist and electrode sheets. By combining the cotton swab water guide with the atomizer, water mist with a high specific surface area reacts with the electrode sheets, thereby improving the efficiency of the electrochemical reaction and realizing continuous power generation without external energy input.
[0005] Technical Solution To achieve the above object, the present invention provides the following technical solutions: A power generation device based on the reaction between water mist and electrode sheets includes an electrolytic water tank, a cotton swab, an atomizer, a positive and negative electrode sheet assembly, and a conductive connector. One end of the cotton swab is immersed in the electrolytic water tank, and the other end is connected to the atomizer. Capillary action conducts the electrolyte solution to the atomizer. The atomizer atomizes the solution into water mist, which then contacts the positive and negative electrode sheets, generating electricity through an electrochemical reaction. This electricity is then conducted through the conductive connector.
[0006] The cotton swab is made of highly water-conductive fiber material to ensure stable water conduction; the atomizer uses small-particle atomization equipment to increase the contact area between the water mist and the electrode; the positive and negative electrode groups are made of materials with excellent catalytic properties to promote electrochemical reactions.
[0007] Beneficial effects
[0008] 1. Simple structure: No complicated pump or drive device is required, and solution transfer is achieved only through the capillary action of the cotton swab and the atomizer, reducing costs and failure rates.
[0009] 2. Efficient power generation: The high specific surface area of water mist significantly increases the electrode reaction interface, improves electron transfer efficiency, and increases power density.
[0010] 3. Green and environmentally friendly: Using water and electrolytes as raw materials, the reaction process does not emit pollutants, which meets the needs of sustainable development.
[0011] 4. Strong adaptability: The device size can be flexibly designed and is suitable for small power consumption scenarios such as portable devices and environmental monitoring sensors. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is a structural schematic diagram of the power generation device of the present invention; Markings in the figure: 1 is the electrolytic water tank, 2 is the cotton swab, 3 is the atomizer, 4 is the positive electrode, 5 is the negative electrode, 6 is the positive terminal, 7 is the negative terminal, and 8 is the electrolytic water. DETAILED DESCRIPTION
[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0014] A method for generating electricity based on the above device, such as Figure 1 As shown: 1. Pour the electrolytic water solution into the electrolytic water tank 1, immerse one end of the cotton swab 2 in the solution, and connect the other end to the atomizer 3.
[0015] 2. Start the atomizer 3 (initially powered by an external power supply) to atomize the solution into water mist and spray it toward the electrode plate group (positive plate 4 and negative plate 5).
[0016] 3. Oxygen ions in the mist oxidize on the surface of the positive electrode 4 to produce oxygen, while hydrogen ions are reduced on the surface of the negative electrode 5 to produce hydrogen. Electrons flow through the positive and negative terminals 6 and 7 to the load, achieving continuous power generation. Once the device is operating stably, it can use its own electricity to power the atomizer 3, forming a self-sustaining system.
